DRAM Supply Modeling Tutorial
This editorial from Chip Strat provides a foundational tutorial on building a simplified DRAM supply model. It explains how to estimate bit production by combining wafer starts, die size, and bit density, using TechInsights' measurements of Micron's 1α node as an example. The article outlines the differences in process node naming between memory (1α, 1β, 1γ) and logic chips, highlights that the leading 1γ node yields about 3.7 TB per wafer compared to 2.1 TB for 1α, and discusses how node adoption varies among Samsung, SK hynix, Micron, and China's CXMT, which lags four generations behind. The upcoming analysis will extend the model to include HBM impact, mix effects, and future capacity growth, aiming to eventually assess how long-term agreements might alter supply incentives.

Key Takeaways & Evidence Grounding
- TechInsights measured Micron's 1α DRAM: die size 25.41 mm², bit density 0.315 Gb/mm² for an 8Gb DDR4 part.
- A 300mm wafer at 1α yields approximately 2.1 TB of DRAM, assuming 85% yield.
- The leading 1γ node has a bit density of ~0.55 Gb/mm², resulting in ~3.7 TB per wafer.
- CXMT's mainstream node is at 1x-1y, four generations behind the 1γ/1c leading edge.
- DRAM process nodes are named differently across vendors: Micron uses Greek letters, while Samsung and SK hynix use Latin letters.
- The article is a tutorial building a toy supply model, not a forecast.

New German Agency Pathos Launches with Jürgen Milski Film
Kevin Claus, Felix Ebell, and Finn-Jordan Max have founded Pathos, a new Hamburg-based agency focused on branded entertainment. The agency's launch film, featuring Jürgen Milski, parodies the 9Live call-in format to critique commodified and forgettable advertising, arguing that ads should be entertaining again. The trio, who previously worked at Jung von Matt or on freelance projects for clients like Samsung, Adidas, and Netflix, will produce an ongoing entertainment campaign. Pathos counts Sparkasse among its first clients and plans to expand across Europe in the medium term.
AI Stocks Plunge, Inflation Heats Up, Yet Opportunities Remain
The article discusses last week's stock market decline driven by AI stocks and hotter-than-expected inflation data. The Nasdaq fell 4.5%, while the S&P 500 dropped 2%. However, solid bank earnings and a rotation into defensive sectors provided some optimism. AI-related stocks, particularly memory chip makers and neocloud providers like CoreWeave, experienced significant losses. Meta and Microsoft showed resilience, with Meta releasing new AI models and Microsoft reaching a record high. The article also highlights the importance of diversification and mentions portfolio adjustments, such as adding to Kimberly-Clark and trimming Cardinal Health.
